Composites Constituants A

This lecture covers the constituents of composites, including polymer matrices, metal, organic, and mineral reinforcements, such as Kevlar and carbon fibers. It discusses the manufacturing processes of fibers like PAN-based and pitch-based, as well as the properties and applications of glass, ceramic, and natural fibers. The lecture also explores the chemical structures of Nomex, Kevlar, and PA 6.6, along with the fabrication processes of pitch precursor carbon fibers. Additionally, it delves into the properties and comparisons of various synthetic fibers like polyethylene, Dyneema, and Zylon. The environmental impact and selection criteria for fibers in composite materials are also addressed.
